I lust you
When a man says 'I love you' just to get you to stop yelling at him. It's not love. It's a desperate attempt to keep his pants on.
'I love you' during a screaming match. It's just a cry for help.
'I love you' when he's about to get kicked out. Temporary insanity.
'I love you' after you throw a shoe at him. He's just trying to survive.
